A registered dietitian wants you to consider these three things if you’re using GLP-1 medications to make sure you’re still meeting your nutritional needs

Key Points:

• Recent research from the University of Cambridge and University College London highlights concerns about the lack of nutritional advice for people using GLP-1 weight loss medications, which can reduce appetite and food variety, increasing the risk of nutrient deficiencies over time.
• Registered dietitian Zoe Griffiths advises those on GLP-1s to increase protein intake to support muscle mass and metabolic health, recommending 60–120g daily with protein included at every meal, possibly through smaller, more frequent meals.
• Fiber intake is also important, as reduced appetite may lower consumption of fruits and vegetables, leading to constipation and gut health issues; Griffiths suggests aiming for 30g of fiber daily from diverse sources or supplements like psyllium if needed.
• Micronutrient deficiencies in magnesium, iron, and calcium can affect energy, immunity, bone health, and cognition; supplements may be beneficial, particularly magnesium for constipation and sleep, and calcium if dairy intake is low, but iron should only be taken if deficiency is confirmed.
• Working with a dietitian or nutritionist to identify individual nutritional needs and develop a sustainable eating plan is recommended for those using GLP-1 medications to maintain long-term health.
